babc8a88a1 clip_clipper_polygon_with_subject_bbox() and diff_clipped() extracted 
from TreeSupports to ClipperUtils to be generally available.
diff_clipped() is an optimized version clipping the "clipping" polygon
using clip_clipper_polygon_with_subject_bbox().
To be used with complex clipping polygons, where majority
of the clipping polygons are outside of the source polygon.

3350292ff2 WIP TreeSupports 
1) Nodes allocated using std::deque, not as std::set of pointers for
   less memory allocator pressure.
2) Parents changed to parent indices, so that one may allocate side
   by side data for nodes addressed by these indices. Thus now elemens
   are being marked as deleted and the whole node database is being
   compacted in one shot instead of deleting an element from std::set.
3) Removed SUPPORT_TREE_ONLY_GRACIOUS_TO_MODEL for simplicity, it was
   never used.
4) Fixed crash when slicing multiple objects with three supports.

2b3d4b2868 WIP TreeSupports: 
1) Reworked the merging code to use an AABB tree for better locality.
   The old code sorted lexicographically, the new code splits bounding
   boxes by the longest axis.
2) Refactored to a functional style with better const correctness.
3) Reduced memory allocation pressure by replacing std::set with
   vectors, in place merging etc.
